Well, Apple may have one of the best dev team. However, as many big companies, they get into a cycle of putting in new features but not improving existing code.
Like this one, cmd+x and middle click with different behavior, is a clear UI inconsistency.
The "issues" of my other suggestions #10830 and #10831, are in Safari too. Those are likely from some universal template, got dropped in and no one border checking if all entries should be in a browser context menu, or if a 2 level menu makes sense at all.
I saw and also work with some big companies. They are more focus on new features than UI improvement. Their dev team more likely to do UI overhaul, as those are more visible projects.
Yes, MacOS/iPadOS (or other big ones) look & feel is a battle tested UI framework, but don't blindly worship their end products.
Also, I am suggesting an option in settings to toggle the behavior, not removing it.
